-
Insert hydraulic rotor <69>/<114> by means of
<E>
into hydraulic
cylinder <58>/<103> so that needle roll <59>/<104> and bore met.
Remove
<E>
(fig. 5-6).
-
Mount disc <70>/<115> and positon over needle roll.
Caution!
Caution!
The control slides at the facing surface of the disk points
towards the slots in the rotor
-
Put up bearing ring <73>/<118> with o-ring <74>/<119>.
-
Clamp the pulse unit slightly in a vice with flat chops.
-
Tighten bearing ring by means of fixture
<C>
until the limit stop.
-
Undo the bearing ring by 360° +90° and carry out the oil filling:
6.6 Oil Filling
1. Begin by filling the impulse unit with syringe
<B>
by way of the drive
shaft, until oil emerges through the seal hole.
2. Assemble the compression spring <77>/<122>, bolt <78>/<123>,
ball<79>/<124>, valve screw <83>/<128> and needle roller <84>/
<129>. Turn the valve screw back gently against the needle roller
(protection against loss).
3. Connect the pulse unit using the adapter
<A2>
to the quick
disconnect coupling.
4. Close the shut-off valve
5. Connect pressure of about 5 bar.
6. Slowly open the shut-off valve fully, until the pressure gauge shows
a vacuum of about 1 mbar (-1 bar).
7. Wait for about 2 minutes, until the number of vacuum bubbles has
substantially reduced.
8. Slowly close the shut-off valve. The pressure gauge shows
atmospheric pressure again, and missing oil is forced into the
pulse unit.
9. Repeat steps 6 to 8, if necessary, until the number of bubbles is
negligible.
-
Disconnect the pulse unit, remove the adapter and add a few drops
of oil with syringe
<B>
.
-
Install the ball <75>/<120> and tighten the set bolt <76>/<121>
(2,9±0,3 Nm).
Caution!
Caution!
The bearing ring <73>/<118> must not turn along!
-
Tighten bearing ring <73>/<118> to the required torque
(8. Assembly Instructions, Fig 7).
-
Fit ball bearing <86>/<131> with the circlip <85>/ <130> into the
housing <88>/<133>. Insert the O-ring <87>/<132>. Push fully
over the long shaft end of the hydraulic rotor.
-
Fit ring retaining ring <89>/<134>. Screw the whole component
onto the pistol grip.
Remarks:
Small bubbles appearing at high vacuum pressure in the
wetting layer between the oil and the material are not
indicating leakage of the pulse unit. The filling result will
not be affected thereby.
6.7 Top up Oil
-
Remove retaining ring <89>/<134>, needle roller <84>/<129>,
valve screw <83>/<128> and ball <79>/<124>.
-
Knock out bolt <78>/<123> and compression spring <77>/<122>.
-
Remove set bolt <76>/<121>. Remove ball <75>/<120> by turning
the drive shaft <69>/<114>, keeping the opening away from the
body.
-
Undo bearing ring <73>/<118> by 360° +90°.
-
Carry out oil filling, see 6.6.
